Also known as "Abstinence Limitation"
The name "Ember Time" was given to Ran Ran. After chasing her sweetheart for so long, she ended up taking care of someone else. He burned his love for that person, and it burned out in the end. That person belatedly came and made him reborn from the ashes.
The name "Abstinence Limitation" was given to He Jun, because He Jun had always been abstinent in the early days and restrained his feelings, which made Shi Ran think that he had been indifferent to his pursuit.
